PPT由于其信息呈现迅速,以及在展示图形、表格、层次、色彩、声音和动画等方面的特殊功能,现在已被广泛应运用于课堂教学,但如果PPT在课堂的实验教学中运用不当也可能会带来一些弊端。对初中科学学科而言,课程以培养学生科学素养为核心,设置有很多学生实验,实验的课堂教学效果会很大程度上影响到学生科学素养的贯彻落实。结合自身和观摩其他老师的课堂实践,笔者认为巧妙地运用PPT这种常见的课堂媒体,是一种提升科学学科实验教学课堂效果的有效手段。如何用好,应注意以下几个方面。
PPT is now widely used in classroom because of its rapid presentation of information and the special features in displaying graphics, tables, levels, colors, sounds and animations, but it may also be useful if PPT is not used properly in classroom experiments Will bring some drawbacks.

The effect of classroom teaching in experiment will greatly affect the implementation of students’ scientific literacy. Combined with the classroom practice of myself and other teachers, I think it is an effective way to improve the classroom effect of experiment teaching in science subject to skillfully using PPT as a common classroom medium. How to make good use, should pay attention to the following aspects.
